+// The following picture shows a typical outcome of call to Draw("all"): 
+// One the left side:
+// - The distribution of the values with the Gauss fit are shown (points connected 
+//   with each other). The line is green, thus the Gauss fit has a probability higher 
+//   than 0.5%.
+// - The distribution of the positions of the maximum (abs. arrival times) 
+//   is displayed. Most of the events have an arrival time of slice 7 (==hardware:8)
+//
+// On the right side:
+// - The first plot shows the distribution of the values with the Gauss fit
+//   with error bars
+// - The second plot shows the TGraph with the events vs. time
+// - The third plot shows the fourier transform and a peak at 100 Hz.
+// - The fourth plot shows the projection of the fourier components and an exponential 
+//   fit, with the result that the observed deviation is not statistical, but signficant with a 
+//   probability smaller than 0.5%.
